Lithuanian Citizenship
Restoration of Citizenship: a right available to children, grandchildren, and great-grandchildren of those who were citizens of Lithuania between 1918 and 1940 and left the country prior to 1990. Unlike other legal frameworks, Lithuania makes no distinction between grandparents and great-grandparents for purposes of transmission.
The right is transmitted equally through male and female lines. The central requirement is demonstrating that the ancestor was a Lithuanian citizen between 1918 and 1940 and left the country before 1990.
NO: Your great-grandfather was born in Lithuanian territory in 1890 but emigrated in 1917, prior to the establishment of the independent Lithuanian State (1918).
Available to descendants of Lithuanians whose ancestors emigrated before 1918, or to great-great-grandchildren not covered under the Restoration pathway. This route is reserved for stateless individuals or citizens of countries that do not permit effective renunciation of their original nationality.
NO: Great-great-grandchild of a Lithuanian citizen who is currently a U.S. citizen (a legal pathway exists for renouncing U.S. citizenship).
